The installation was not as smooth as we would like. That tree thing wasted us quite a bit of time.
We spend a lot of time finding the best routing location for all tubes under the compressor. On top of that, we need to but a new smaller diameter hose (much more flexible) to work with the smaller than expect inter-cooler coupling, and we also have to machine 4 hose couplings reducer to work with the new hoses. Overall, installation was easy. Car fire up nicely and not problem spotted for the 15 minutes of idle and 5 minutes of driving in the parking lot. I will do some data logging tomorrow for further diagnostic.
Once again, thanks for all your input..
